Hi !I know reading is pain but please i need your help.

I have just finished a database application and know i'm in a bit of a trouble with the setup.

Using the .Net setup utility isn't enaugh because i need to make some database initialization and i really don't know how to 'comunicate' with the setup not just placing files in certain directories ...

So here's what i tried to do:
1.I made a small c# application some kind of SetupWizard for my database that makes some small checkes(It finds all the SQL Servers and all the Databaseses on the selected server etc...etc)
2.No i need to run the SQL scripts but first i need to place them
;so my wizard calls the setup(made with the .Net setup utility project)
3.Now the big problem is where are these files since this installation part was not under my control

If only i could configure the Setup to write into a registry key the path to the files .
There must be a place where the system keeps the path.I hope it's not in the uninstall file.I don't know how to read it

THX!
